Hub cap with oil level indicator

Abstract

Aspects of the invention(s) described include: a system including: a hub cap including a central axis defining a rotational axis for the system; an indicator window including an indicator portion coaxially aligned with the central axis; and an indicator subsystem. A variation of the system can include an indicator subsystem with a float mechanism defining an indicator resolution; a shaft aligned with the central axis, wherein a first float of the float mechanism rotates about the shaft and wherein the first float includes a first lobe, a first counterweight, and a marking; and a mask defining an opening through which the marking can be observed. The invention(s) allow oil level within an oil reservoir of a hub cap to be observed, even when an inflator is interfaced with the hub cap for inflating a tire of an associated wheel.
